Me and My friend did not die we killed the Gauntlet and after the fight was over all of just his Armor was gone nothing else just the 4 pieces. Please Help!

I fought with it 10 mins ago and once i got hit by its ray and got killed my entire armor disappeared. It was dragon scale armor on full durability so i think something is wrong here :/

sorry, i don't know what dragon scale armor is - can you send me the combination of mods that you saw the issue
